Abstract

The utility model relates to an auxiliary tool in the field of metal processing, in particular to a roll caliber auxiliary cooling device of a continuous mill. The roll caliber auxiliary cooling device of the continuous mill is used for carrying out auxiliary cooling on a roll caliber of the continuous mill. The roll caliber auxiliary cooling device of the continuous mill comprises an arc-shaped spray pipe fixed on one side of the roll caliber, and spray nozzles are arranged on the sidewall of the spray pipe. A spout is arranged in the center of each spray nozzle and is in alignment to the roll caliber. The cross section of each spout is of an irregular figure. The roll caliber auxiliary cooling device of the continuous mill overcomes the defects that round spouts and rectangular spouts are too small in cross sections and too big in water pressure at the spouts in the prior art. Meanwhile, the water flow at the spouts is increased, and the cooling efficiency is improved.

Description

Continuous rolling mill roller pass radiator cooler
Technical field
The utility model relates to a kind of aid of metal manufacture field, specifically, relates to a kind of continuous rolling mill roller pass radiator cooler, is used for the auxiliary cooling to the continuous rolling mill roller pass.
Background technology
At the metal manufacture field, tandem mill is widely used as a kind of common equipment.Vertical continuous mill mainly is comprised of roll, frame, guide and guards, roller gap adjusting device, water cooling device for roller etc., and water cooling device for roller is installed in around the roll, is mainly used in the cooling of breaker roll pass.
Roll pass refers to, adds at roll and draws the worker and go out groove, and the groove of two or more rolls is assembled up accordingly, forms roll pass, during rolled steel tube, jointly forms roll pass by upper bottom pass and plug.When rolling, rolled piece passes through a series of passes, thereby obtains corresponding wire rod, tubing or shaped steel.Because in the operation of rolling, rolled piece is rolled in pass, therefore, the temperature of roll pass can raise, and roll pass is worked under long-term hot environment, can greatly reduce its service life, therefore, need the breaker roll pass to carry out cooling processing, in the prior art, usually by water cooling plant it is cooled off.
Water cooling device for roller is as a kind of radiator cooler of continuous rolling mill roller pass, its basic use principle is: the sparge pipe sidewall of arcuation is provided with several nozzles, nozzle central authorities are spout, spout is aimed at roll pass, after starting water cooling device for roller, cooling water is poured into the roll pass from the spout of water cooling plant, directly it is carried out surface cool, prolongs its service life.But in the prior art, the problem that water cooling device for roller exists is, if the spout section is circular, then carry out a cooling by circular spout breaker roll pass, film-cooled heat is little, easily causes inhomogeneous cooling even, cause the roller surface slight crack, reduce the rolling tonnage of roll in actual production, and need the frequent pass, cause simultaneously the rising of defect rate.Simultaneously, circular spout is because its section is little, so nozzle hydraulic pressure is larger, and the water that is injected in the roll pass surface by spout usually can launch, and has reduced cooling effect.Its section is little, also easily causes spout to stop up, and impact is produced.And there are similar problem in flat-shaped (rectangle that flat length-width ratio is larger) spout and circular spout, and namely the spout section is little, and hydraulic pressure is large, and the water that is injected in the roll pass surface by spout usually can be returned by reflection shot, affects cooling effect.
Mentality of designing of the present utility model just is, overcomes circular spout and flat-shaped defective in the prior art, and the shape of spout is made certain improvement, develops a kind of continuous rolling mill roller pass radiator cooler, is used for the auxiliary cooling to the continuous rolling mill roller pass.
The utility model content
The purpose of this utility model is, a kind of continuous rolling mill roller pass radiator cooler is provided, and is used for the auxiliary cooling to the continuous rolling mill roller pass.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of continuous rolling mill roller pass radiator cooler, comprise the arcuation sparge pipe that is fixed in roll pass one side, the sidewall of described sparge pipe is provided with nozzle, and described nozzle central authorities are spout, described spout is aimed at roll pass, and the section configuration of described spout is irregular figure.
The section of described spout is the cross spout.
The section center of described spout is circular spout, and described circular spout periphery is surrounded by an oval ring spout.
The section center of described spout is circular spout, and described circular spout periphery is surrounded by a rectangular slot shape spout.
The beneficial effects of the utility model are:
1. irregular nozzle configuration has overcome circular in the prior art and the rectangular jet section is too small, and the problem that nozzle hydraulic pressure is excessive simultaneously, has also increased the flow of nozzle water, has improved cooling effectiveness;
2. both increase film-cooled heat, effectively avoided again the cooling water flight of middle circular nozzle, through the test of many times checking, reached the cooling effect of expection;
3. structure is comparatively simple, and principle is simple, easily realizes.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model continuous rolling mill roller pass radiator cooler;
Fig. 2 is that the A of nozzle among Fig. 1 is to one of zoomed-in view;
Fig. 3 is that the A of nozzle among Fig. 1 is to two of zoomed-in view;
Fig. 4 is that the A of nozzle among Fig. 1 is to three of zoomed-in view.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment one: referring to Fig. 1, and Fig. 2.
A kind of continuous rolling mill roller pass radiator cooler, comprise the arcuation sparge pipe 1 that is fixed in roll pass (not shown) one side, the sidewall of described sparge pipe 1 is provided with nozzle 2, described nozzle 2 central authorities are spout 3, described spout is aimed at roll pass, inventive point of the present utility model is, the Section Design of described spout 3 for being different from shape of the prior art, namely is designed to irregular figure.
In the present embodiment, with the section cross spout of described spout 3.
The shape of cross spout has overcome circular in the prior art and the rectangular jet section is too small, and the problem that nozzle hydraulic pressure is excessive simultaneously, has also increased the flow of nozzle water, has improved cooling effectiveness.
Embodiment two: referring to Fig. 3.
The present embodiment and embodiment one are basic identical, do not give unnecessary details, and difference only is, in the present embodiment, the section center of described spout is circular spout 4, and described circular spout 4 peripheries are surrounded by an oval ring spout 5.The cross section diameter of circular spout 4 is designed to cross section diameter greater than prior art, simultaneously by regulating the slit width of oval ring spout, the hydraulic pressure of oval ring spout 5 is designed to be slightly larger than the hydraulic pressure of circular spout 4, both increase film-cooled heat, avoided again the cooling water flight at middle circular spout 4 places.Improved cooling effectiveness.
Embodiment three: referring to Fig. 4.
The present embodiment and embodiment one are basic identical, do not give unnecessary details, difference only is, in the present embodiment, the section center of described spout is circular spout 4, and described circular spout periphery is surrounded by a rectangular slot shape spout 6, and the present embodiment only is the simple distortion of of embodiment two, principle is identical with embodiment two, is not repeated herein.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection domain of the present utility model.
